Your eyes did not deceive you, that actually was the sun for about an hour in the afternoon. It was the result of the cold front moving overhead, mixing the airmass just enough to break up the fog for a brief moment before it filled back in and will be thick again overnight tonight. Lows once again will fall into the low 30s with some small areas of patchy freezing fog.

The valleys will be back to fog for the remainder of the weekend while the coast and mountains are back to mostly sunny skies and highs climbing back into the low to mid 50s. Visibility will suffer (along with the air quality) as the high pressure ridge rebuilds thickening up the fog and creating another inversion for the weekend. However, it doesn’t look to be as strong as earlier this week but still, sunshine for the valleys will be hard to come by.

Air Stagnation Advisories continue through Sunday evening for the Willamette valley as the dense fog (if it happens to break some) will likely be back early next week as the high pressure ridge rebuilds. This year is likely going down as one of the drier that Oregon has seen in quite some time.
